Developed the architectural foundation for experimental Azure backend support in the gruntwork-io/terragrunt repository, enabling early recognition of the azurerm backend within Terragrunt’s workflow. The work introduced an azure-backend experiment flag and a stub backend implementation, embedding CommonBackend to prepare for future features such as bootstrap, delete, and migrate operations. All changes were implemented in Go, with comprehensive documentation updates in Markdown to clarify the experimental status and guide users. The approach emphasized maintainability by refining test organization and updating backend documentation, setting the stage for future SDK integration and production-ready Azure backend capabilities in subsequent development cycles.
